E2M1 has an odd, interesting winding staircase that opens into a hellish pit. It's crap otherwise - a typical 1994 level (October 1994 in this case), garish and badly-made. E2M2 is a novelty boss level with another winding staircase and some cyberdemons; you can run through it. E2M3 has an eye-straining hallway and not much else. E2M4 has some clever, odd underground caverns, although they are extremely frustrating to walk along. Too much surreal.
